My eyes are already starting to glaze over, and I'm not
even halfway through the section. Could we get a
@lilypond in here? Ideally a @lilypond showing all
methods of setting these things, but at the minimum
showing just one method.

Graham,
Is this better? I added two examples, but there's the
obvious problem of \paper variables being ignored from
within a @lilypond. CG 4.3.4 says:
If you are making an example demonstrating special
\paper{} values, contact the Documentation Editor.
Consider yourself contacted!
